“…Training methods have included: feedback about the trainee's performance (e.g., Bouchard et al, 1980;Carlson, 1974;Fyffe & Oei, 1979;Payne, Winter, & Ball, 1972;Rickert & Turner, 1978); videotapes (e.g., Eisenberg & Delaney, 1970;Powell, 1975;Taber, 1976); instructions (e.g., Eskedal, 1975;Perry, 1975); behavior rehearsal (e.g., Bailey, Deardorff, & Nay, 1977;Gladstone & Sherman, 1975;Levine & Tilker, 1974); modeling (e.g., Eskedal, 1975;Frankel, 1971; Goldberg, 1971;Hart, 1973;Saltmarsh, 1973); and audiotapes (e.g., Danish & Hauer, 1973;Sigal & Levin, 1976;Silverman & Quinn, 1974). A number of other studies has shown the superiority of multicomponent training packages which have combined several training methods such as modeling, instructions, rehearsal, videotapes, and feedback in producing reliable improvements in trainee skills (Bailey et al, 1977;Bouchard et al, 1980;Dancer et al, 1978;Eisenberg & Delaney, 1970;Fabry & Reid, 1978). Because no specific technique has been found to be the most, or only, effective technique, the use of multiple-training techniques would appear to ensure maximally effective training.…”
